PHOTOSHOP - Bug within "Slice Options" edit window on MacOS 10.10

Found a bug in CC version 2014.2.2, running on Mac OS X Yosemite version 10.10.2

When editing in the "Slice Options" window, hitting control + Z crashes the window and erased the data you entered, giving the error: "undo: NSCellUndoManager 0x60800048e20 is in invalid state, undo was called with too many nested undo groups". I have recreated this problem every time, without fail.

Additionally, there also seems to be an issue in the "Slice Options" window where when you paste text data into the fields you have copied from somewhere else (e.g. TextEdit), the pasted text does not appear until you click into another data field.

Not major problems, but majorly annoying when you work with a lot of slices and are used to hitting control + Z when you make a mistake. :)

I was able to reproduce this in MacOS 10.9.5 as well.
It is something specific to that dialog.
The good news is that I cannot reproduce the problem in our current builds - so this should be fixed in the next release.
